... using the instantaneous CO level and the COHb concentration from the end of the previous interval. The 15-minute HCN average was a running average calculated at the end of each data interval.

... In 2005, the Department of Defense requested that the National Research Council assess the Army's proposed guidance for assessing the adverse effects resulting from the combined simultaneous exposures to low-levels of CO and HCN. The potential for combined exposures results from routine firing of guns in enclosed but ventilated spaces in the military environment such as armored tanks.

... THE COMMITTEE'S FIRST REPORT The committee divided its work into two reports. In the first report due by September 2007, the committee considers whether the hazards presented from combined exposures at low levels warrant a combined assessment.
